Glass Furnace Control

Glass melting and fining is a delicate balance between energy efficiency, glass quality and maximum throughput keeping emissions within legislative boundaries. Changing composition raw materials into a molten glass that meets the needs of production is one of the most complex processes in the industry.

Extreme dead times and sometimes frequent pull rate fluctuation of the glass furnace makes the control of the furnace process complex. As the furnace is one of the most expensive resources for a glass manufacturing plant, stable and smooth control is a must, capable of keeping all parameters inside their narrow boundaries, as this will have a positive effect on the furnace lifetime.
